Reading device for receiving authentication information through user interface to permit cancelling ongoing pull scan

A reading device comprising:

• a scanner;
• a user interface;
• and
• a controller,
• wherein the controller is configured to perform:
• receiving an execution instruction issued from an external device, the execution instruction instructing the controller to perform a pull scan, the pull scan including:
• controlling the scanner to read an original to generate scan data based on the original;
• and returning the scan data to the external device;
• starting a first pull scan, the first pull scan being the pull scan based on the execution instruction and started under a pull scan start condition, the pull scan start condition including a requirement that first user authentication information is received in association with the execution instruction;
• and
• cancelling the started first pull scan under a first cancellation condition, the first cancellation condition including:
• a requirement that a cancellation instruction to cancel the pull scan is received through the user interface after starting the first pull scan;
• a requirement that second user authentication information is received through the user interface in association with the cancellation instruction;
• and a requirement that the second user authentication information corresponds to the first user authentication information received in association with the execution instruction,
• wherein despite receiving the cancellation instruction after starting the first pull scan, the controller continues the first pull scan under a first continuation condition, the first continuation condition including:
• a requirement that the cancellation instruction is received through the user interface;
• a requirement that the second user authentication information is received through the user interface in association with the cancellation instruction;
• and a requirement that the second user authentication information does not correspond to the first user authentication information received in association with the execution instruction.
